Backhoe Need Assistance with nh 757C

Don Hale · Mar 14, 2010

I really need some guidance, and hope that I have not made a major mistake!

I just bought a NH 757C backhoe for my 2003 NH TC 30. The Bh is still at the sellers house 140 miles away. I need to get my tractor plumbed and mounts attached so I can trailer the tractor for pick up. The problem, WHen I looked at the front mounts, it appears to me that it bolts up where the 7308 loader is attached. I will crawl under the rear of the tractor tomorrow am

The hydraulic in the rear is not where he or the manual states ( behind right rear fender) Nothing there like he described. So I am in a major quandry for a dummy!.

As you can tell I need assistance on rear connection so I can disconnect the 3PH, and how to "T" into the front hydraulics, I did not get the instructions or paperwork. the only thing I have found so far has come from internet research.

Any assistance would be greatly appreciated! Thanks

Don,

You will have to connect to the PB (power beyond) line from your loader valve. You don't "T" this connection. Fluid will flow from pump thru front loader valve to backhoe then to return. This configuration will make the 3 pt. hitch and remotes inoperable with the backhoe attached, this is normal for New Holland. The return will be on the aft axle housing near the remotes.

You will probably get more info. if you post this in the New Holland specific forum. You can also search on; backhoe, 756C, 757C, 758C, TC-45 etc. I know there is a long thread on connecting a backhoe on a TC-45D. If after reading on your searches and you have questions just let me know. I can send pics relating to a 757c on a TC-45.

Goto Newholland.com
Goto Agriculture--- North America on the site.
Then under "parts" click "search for parts"
When you type in 757 it will bring up all the parts diagrams.
Works great!
